How do great white sharks benefit the environment

I added an answer that was missing to the Answers.com Database and wanted to catalog it here.

"Since Great White sharks are Apex predators, all they really do is control the populations of animals beneath them.

That control would then lessen the burden on the environment of too many fish taking too much of the oceans resources.

So it helps conserve nutrients and it keeps other animals in check. Besides that though it seems to serve no other purpose as far as I'm aware."
